To all whom it. may concern."

Be it known that I, CnARLEs l/V. BECK,

a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Priming Cups, of which the following is speci fication, reference being had therein to the accompanying drawings.

This invention relates to priming cups and said invention consists in the structural features and arrangement of parts hereinafter described and illustrated in the accompanying drawing, wherein;

Figure 1 is a sectional elevation with one embodiment of the invention;

Figure 2 is a view of the same in side elevation; I

Figure 3 is a cross section on line 33 of Figure l, drawn to an enlarged scale;

Figure 3 is a sectional view similar to Figure 1 but showing a slightmodification of the arrangement in Figure 1; V

Figure 4 is a vertical sectional elevation of another embodiment of the invention;

Figure 5 is a side view of the same;

Figure 6 is an enlarged sectional detail of a portion of Figure 4.

In these views, and referring more particularly to Figures 1 to 3 inclusive, 1 designates a priming cup having a reduced tubular downward extension which is interiorly threaded just below the'cup proper as indicated at 2. The lower end portion of said extension is preferably reducedto a somewhat greater extent than said threaded portion 2 and is exteriorly threaded as indicated at 3 to function as a nipple for mounting said cup. Said downward exten sion has an integral bottom member 4 having a discharge port 5. 6 is a valve member formed by a stem bevelled at the lower end to engage a valve seat formed by the margin of the port 5. Said stem projects upwardly out of the cup 1 and is bent laterally to form a handle member 7 whereby said stem may be turned- At an intermediate point, the'stem 6 is formed with an enlargement 8 which is screw threaded to engage the threads 2 of the cup. The enlargement 8 may be produced upon the stem 6 in any desired manner preferably being formed by an upsetting process through 'a press opera tion. The enlargement 8 is formed at opposite sides of the stem 6 with vertical passages 9 providing for the down flow'of the priming fluid from the cup proper to the lower portion of said extension. From the preceding description, it will be evident 5 that upon rotation of the stem 6 by means of its handle? the valve forming lower end of said stem will be raised or lowered from its seat due to the screw threaded engagement of the enlargement'S with the threads I 2 of the cup.

The construction shown in'Figure 3" con forms to the preceding description except for-the fact that the valve forming stem 10 has a relatively short-portion 10 extending below the enlargement 10 ,the seat 10 for said valve member being in this Preferably the valve member is annularly grooved adjacent its upper end asindicated i at 15 and a portion 16 of the enlargement 13 is swaged into the groove 15 to hold said valve member inserted in saidsocket. Thus, the parts 11 and 12 together form a valve element corresponding to the element I 6 of the Figure 1, Whichelement has an intermediate portion enlarged and screw threaded to engage an interiorly threaded portion of the cup. In this form of the invention, however, there is no increasedrestrictions in the downward tubular extension below thev interiorly threaded portion thereof. A ported valve seat engageab-le by the lower end of the valve member 11 is formed by upsetting the lower end of the extension 17 as is indicated in dashlines at 18inFig.4. j

The described invention in any of its 'sev-. eral embodiments is adapted to be manufactured inexpensively and is of a standard and simple construction such as may not be easily damaged or rendered inoperative.

"What I claim as my invention is: e

1. In a priming cup, the combination with a cup forming member having a reduced downward extension formed with a discharge passage and having a valveseat in said passage and a threaded portion above said seat, ofa valve member having an enlarged portion threaded to engage said threaded portion of the extension having 'an operating portion extended above said cup forming member and-having a portion extending below said threaded portion to I engage said valve seat, the lastmentioned portion being spaced from the surrounding wall of the discharge passage, the threaded portion of the valve member having a passage therethrough for the down flow o'f'the priming fluid from the cup proper.

2. In a priming cup, the combination with a eupforming member having a reduced downward extension formed with a dis charge passage and having a valve seat in said passage and a threaded portion above saidseat,iof a valve member having an en larged portion threaded to engage said .threaded portion of the extension, having portion of the valve member having a passage therethrough for the down flow of the priming fluid from the cup proper.

3. In a priming cup, the combination with tension being interiorly threaded and 1 the lower portion of sa d extension being formedwith a valve seat, of a valve member comprising a portion engaging said seat and an operating portion having a handle above the cup forming member, said operating portion having anenlarged threaded portion engaging the threaded portion of said cup forming member and formed with socket engaged by the upper end of said valve member. v

l. In a pri-niiing cup, the combination with a cup forming member having a reduced downward extension formed with a, discharge passage, said passage having an interiorly threaded portion and'a :valve seat at a point below said threadedportion, of a valve member comprising upper and lower members, having permanent telescopic engagement, formed wit-han enlargement screw threaded to engage said threads of said extension, the lower element of the valve member being engageable with said valve seat and the upper element thereof being formed with an operating handle. v V

In testimony whereof I afiix'mv signature.
